Place it at the exact beat where a brag peaks in your edit, after a short setup clip. Follow it with the awkward moment sound for a second reaction, or swap in eh eh ehhhh for another voice in the exchange between friends.
About this sound
This nine-second clip is a drawn-out moan from someone called Viktor, delivered as a single groaning vocal performance that keeps going longer than expected. It feels awkward and deliberately overdone, turning a small reaction into something uncomfortable and funny at the same time for anyone listening in.
